First, let me spectrum for everyone in pediatrics. What is blue light?
Medium and short wave blue light is a type of light with relatively high efficiency energy in the wavelength range of 400nm-480nm. The blue light within this wavelength can increase the endotoxin level in the macular area of the eye, seriously endangering the physical and mental health of the eyes.
The long-term impact of "blue light"
The retina is protected by the following factors: macular pigment, antioxidants, melanin, vitamins, and cellular self-renewal. Over time, the natural protection of the body weakens, the protection of the retina weakens, cellular metabolic waste accumulates (lipofuscin), and harmful free radiation is produced, leading to premature aging of the retina and an increased risk of age-related macular degeneration. At the same time, an increase in average life expectancy and exposure to sunlight in daily life also promote weakened retinal protection.
What is the source of blue light?
There are various sources of blue light in daily life, including LED lighting, tablets, televisions, computer displays, and smartphones. These types of electronic products will expose us excessively to blue light.
How to prevent blue light?
The best way to reduce blue light intake is to try to avoid using machine devices such as mobile phones and computers. However, in this era of information content and professional knowledge explosion, mobile phones and computers are the most common machine devices for obtaining information and professional knowledge. Leaving them can be said to be difficult!
Another way to reduce blue light intake is to wear anti blue light glasses, which filter the blue light into the eyes and reduce the damage of blue light to the eyes. At present, there are many manufacturers of myopia glasses with excessive blue light in the sales markets of various countries around the world. The quality of the anti blue light myopia glasses produced is also uneven, and even inferior manufacturers choose fake and inferior lenses. Not only can they not prevent blue light, but the problems of the lenses themselves may also cause other damage to the eyes; Realistic and reasonable anti blue light lenses with high cost-effectiveness have a relatively high market price, but it is not necessarily true that a high priced lens is a high cost performance lens. Those who need it must carefully check before making a purchase, and try to purchase products produced and manufactured by major manufacturers to ensure relative quality.
